Method 3: Update Chrome

Chrome is no stranger to SSL certificate bugs. One of the more recent bugs is appearing in Windows 7 leaving Google Chrome users struggling to access its services.

  • Let Chrome check for updates then follow on-screen prompts 
  • Chrome will install the updates if there are any
  • Restart Chrome once it’s done and check the website again

Method 4: Disable SSL/TLS Protocol Filtering

As we’ve mentioned, third-party software can cause conflicts with Google Chrome and it’s security features. Antivirus programs and firewalls that support SSL/TLS protocol filtering can cause issues in Chrome with it thinking the website is bad.

The issue was resolved by disabling the SSL/TLS protocol filtering from their antivirus settings. Each antivirus software is different, but you can find the setting in the advanced menu and look for a setting related to SSL/TLS filtering. Turn it off and restart your computer. Check to see if the error is resolved. 

Method 5: Clear Browsing Data

When you visit a website the information is saved in a cache. This can clog your browser and cause various issues within Chrome. It saves the information for the next time you visit the website.

It will help it load quicker and save the information you may have put on the website. You can clean this, however, and here’s how: 

  • Open Chrome and click on the three dots in the corner
  • Choose Settings
  • Find Advanced and click on it
  • Find Privacy and Security

  • Check each box other than Passwords and other sign-in data  as well as Media licenses
  • Click on Clear data and wait a few seconds
  • Restart your computer and try the website again

Clear Browsing Data

Method 6: Fix Third-Party Software Conflicts

As we have said before, antivirus software programs can cause issues with your computer and Chrome.

For some reason, these antivirus programs can think that a certain webpage is malicious or non-credible and block access to the website when it’s perfectly fine. To fix that, you should turn off your third-party software applications to see if it fixes your issue. 

Method 7: Remove Extensions

Extensions you have added to Chrome or may have found its way onto your browser could be creating some issues with certain webpages. Malicious software can add its extensions as well. To remove these extensions, follow these instructions:

  • Navigate to More tools 
  • Click Extensions
  • Click on the recycle bin and choose to Remove
